Description

There are several free software games available built with the libGDX framework.

Some examples:

Burger Party: https://agateau.com/projects/burgerparty/ and https://github.com/agateau/burgerparty
Klooni 1010!: https://lonami.dev/klooni/ and https://github.com/LonamiWebs/Klooni1010
Apple Flinger: https://gitlab.com/ar-/apple-flinger
Poland can into Space: https://github.com/JSandomierz/pcis

You can type "libgdx" into the search bar at https://mglapps.frama.io to get a list of 13 free software games based on libgdx.

The big advantage with these games is:

they run on Android, so they are adapted to phone screens with touch input (almost all are available on FDroid)
they could also run on desktop platforms, with some of the apps already providing .jar archives (e.g. see https://github.com/LonamiWebs/Klooni1010/releases/tag/v0.8)

The problem:

the .jars can not be run on smartphones like the PinePhone because the .jar builds do not contain the library libgdx.so for the right target architecture

The solution:

get libgdx.so for the right architecture integrated into the .jars during build time
maybe this is only a configuration issue (not determined yet)

I am going to close this task as it is more of libgdx or application specific issue then the Plasma Mobile itself.
